Enum ChargePhase 

pub enum ChargePhase {
    None,
    Trickle,
    Fast,
    Taper,
    TopOff,
    Done,
    // some variants omitted
}

Describes the active charging phase of the charger hardware.

Lithium-ion battery charging typically transitions across distinct stages: Pre-conditioning/Trickle -> Constant Current (Fast) -> Constant Voltage (Taper) -> Top-off -> Done.

Variants

None

The charger is idle, off, or not supplying charging power to the battery (including during passthrough, bypass, or charge-inhibit mode).

Trickle

Pre-qualification / trickle charging phase. Used when the battery is deeply depleted below the pre-charge voltage threshold; current is limited to a small, safe level to restore cell voltage before fast charge.

Fast

Constant Current (CC) fast charging phase. The charger acts as a regulated current source supplying maximum programmed fast charge current.

Taper

Constant Voltage (CV) taper phase. The battery voltage has reached the regulation target limit; current naturally tapers down as the cell saturates.

TopOff

Top-off charging phase. Low-current charging stage right after the CV termination threshold is reached, providing a timed saturation before stopping.

Done

Charge termination complete. The charger has completed its charging cycle (e.g. top-off timer or termination-current threshold reached) and has cut off charge current to the battery while continuing to supply system load. The charger may automatically re-enter FAST if battery voltage decays below the recharge threshold.

impl StructuralPartialEq for ChargePhase

impl TypeMarker for ChargePhase

type Owned = ChargePhase

The owned Rust type which this FIDL type decodes into.

fn inline_align(_context: Context) -> usize

Returns the minimum required alignment of the inline portion of the encoded object. It must be a (nonzero) power of two.

fn inline_size(_context: Context) -> usize

Returns the size of the inline portion of the encoded object, including padding for alignment. Must be a multiple of inline_align.

fn encode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and encoding requires no validation. When true, we can optimize encoding arrays and vectors of Self::Owned to a single memcpy.

fn decode_is_copy() -> bool

Returns true if the memory layout of Self::Owned matches the FIDL wire format and decoding requires no validation. When true, we can optimize decoding arrays and vectors of Self::Owned to a single memcpy.

impl ValueTypeMarker for ChargePhase

type Borrowed<'a> = ChargePhase

The Rust type to use for encoding. This is a particular Encode<Self> type cheaply obtainable from &Self::Owned. There are three cases:

fn borrow( value: &<ChargePhase as TypeMarker>::Owned, ) -> <ChargePhase as ValueTypeMarker>::Borrowed<'_>

Cheaply converts from &Self::Owned to Self::Borrowed.
